When the potatoes are about 6 weeks from planting and are doing well and are about 30cm high, do I trim off the lower leaves before banking up. Next question is.............as I have a lot of 10 litre plastic drums, if I cut the bottom out of these, can I put them over the plant and start to 'Bank-up' inside them.

Don't bother removing lower leaves just heap up soil.You can use buckets over plants ,I would make sure soil drains well with some compost and handful of blood and bone .

Told cannot grow Potatoes in Tyres how about growing in 55litre plastic garbage bins with bottoms cut out and Air holes in the sides, do not have a large area to use. Need help before time runs out, Live in Temperate Zone. PLEASE THANK YOU QUICK .

They will grow fine in bins. You don't need holes in the side. You could just make some drainage holes in the bottom instead of cutting the base right out.

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
